4"x4"x16" NaI(Tl) Scintillation Detector

The Model NAI4/4/16P3.5 Scintillation Detector is a hermetically sealed assembly which includes a high resolution 4″x4″x16″ NaI(Tl) scintillator, a 3.5″ Hamamatsu photomultiplier tube(CR366), an internal magnetic/light shield, an stainless steel housing and a 14-pin connector.

This kind of 14-pin NaI(Tl) detectors have good energy resolution(≤8.5%@662keV) and stability, their standard 14-pin connector can be easily inserted in plug-on photomultiplier tube(PMT) base or digital Multi-Channel Analyzer(MCA) for Gamma-ray detection systems.
